Frequently Asked Questions:
Question: How does the Rigol DM858 differ from other digital multimeters?
Answer:
- Touchscreen: While the touchscreen has become almost standard on oscilloscopes, spectrum analyzers and VNAs, there are still relatively few DMMs with this feature. In the meantime, however, intuitive touch operation of devices using gesture control from smartphones has become so common that it makes sense to equip more and more measuring device categories with it, as far as it makes sense and allows more convenient operation. This is why the Rigol DM858 has a 7"/17.8 cm graphical touch display, which can be used to visualize the data as a trend plot, histogram or bar graph in addition to the numerical display of the measurement results.
- Design: Due to the larger display, the Rigol DM800 looks more like an oscilloscope than a classic DMM. However, it is very flat (266 x 165 x 80 (mm, WxHxD)) and light (<2 kg), making it easy to transport and suitable for mobile use.
- Power supply: Instead of a built-in power supply unit (which takes up internal space) or a dedicated external power supply unit (which can easily get lost), the Rigol DM858 relies on USB: It can be supplied with power via its USB Type-C interface using a standard USB power supply unit (power interface Type-C, DC 12 V/3 A, max 10 W).
Question: What are the most important key specs of the DM858?
Answer: In brief - 5.5 digit resolution, 125 readings/s, data logging up to 500,000 points and measurement of DC and AC voltage, DC and AC current, AC true RMS, 2- and 4-wire resistance, frequency, period, continuity, diode, capacitance, and sensor measurements (temperature: thermocouple J, K, T, E, R, S, B, N, RTD, thermal, user definable DCV, DCI, 2-/4-wire and frequency sensors).
